Valve arrangement in a feed line to deliver fuel from a tank to an internal combustion engine

摘要

A first valve (50) has a movable valve head (51) to seal an outlet (56) from an inlet (53) in a valve housing (511). The valve is in a closed position when there is no feed pressure from a feed pump provided in a feed line. A second valve (60) arranged coaxial with the first valve, opens to a direction opposite to a feed direction when the pressure in the outlet is larger than the feed pressure. Independent claims are also included for the following: (a) a feed system for internal combustion engine; (b) and a vehicle.
